To all it may 0mm l Be it known that I, GEORGE W. BARTLETT,

a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new. and useful Improvements in Burners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in burners and has, relation more par-, ticularly to a device of this general charac tenwherein a liquid-fuel isv atomized and delivered in the formof spray through the medium of an expansiblefluid; and the object of the invention is, to provide a device of this type having novel and improved means whereby the liquid fuel and the eX- pansive fluid are adapted to coact insuch a manner as to result in a maximum of efiiciency.-

The invention consists in the details of better understood, I will now proceed to de-.

scribe the same with reference to the accompanying drawings, wherein Figure 1 is a longitudinal sectional view taken through a burner constructed in accordance with an embodiment of my invention, the delivery tube positioned therein being shown partly in elevation; F 1g. 2 is a sectional view taken substantially on the line 22 of Fig. 1; Fig. 3 is an enlarged rear elevational View of the casting comprised in the invention as herein disclosed; Fig. 4 is a front elevational view of the casting; and Fig. 5 is a fragmentary longitudinal section taken through the inner end of the casting and illustrating in detail certain features of the invention as herein embodied.

As disclosed in the accompanying drawings, 1 denotes an elongated cylindrical conduit of predetermined dimensions having engaged with one extremity a casting C substantially rectangular in form and having one extremityprovided with the integrally connected annular flange 2, the inner wall 3.

whereof being threaded in order that a con-. venlent Connection may be had with an extremityof the conduitl. The casting O is hollowand is divided into thev substantially rectangularcompartmentsa and Z) through the; medium of the septum. or partition 4. The inner. end wall 5 of the compartment a has produced therein an opening 6 in communicationwith the recess or pocket 7 .pro-, duced in said wall 5: and the, adjacent end of the septum 4 and inwhich is adapted to be engaged the extremity of a fuel delivery pipe 8 which extends through. the conduit 1 and is adapted toybe connected with a suitable source of fuel supply, and it"is to be observed thatthecompartment a is of'a depth materially less than the diameteru-of the bore of the pipe 8. As is believed to be self-evident, the fuel delivery pipe 8 is of less transverse diameter thanthat of the conduit 1 whereby a space 9 isalforded, for a purpose which will hereinafter be more particularly referred to.

The opposite extremity of the conduit 1 has engaged therewith a T coupling 10 through the outer extremity of which is di- I rected the delivery pipe 8, the inner extremity whereof being threaded, as herein disclosed, within the recess 7, hereinbefore referred to. The outer extremity of the coupling 10 has its periphery threaded, as indicated at "11, and which is engaged by the packing nut 12 through which the delivery pipe 8 projects and whereby a hermetical connection is assured.

Operatively connected with the lateral I member 14: of the coupling 10 is a conduit 15 leading from a suitable source of expansive fluid, such as steam or air, which travels through the conduit 1 within the space 9 and through the compartment 6 within the casting C and through the restricted mouth or slot 18 produced in the outer wall of the compartment 6 and'of an extent slightly in excess of the interior transverse diameter of the compartment 6. It is also to be observed that the forward wall 16 of the compartment 2) is substantially semi-circular in form whereby a maximum of efficiency of the spray of the device may be attained. The outer face of the compartment a is open, asindicated at 17, and of substantial rectangular formation and it is to be observed that the opening 6 is materially smaller than the transverse diameter of the recess 7 whereby the operation of the burner is greatly facilitated. It

cility with which it may be assembled, and it' will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim: I 5

A device of the character described comprising a hollow casting divided longitudi-- nally into two compartments of substantially rectangular form, the forward face of one compartment being open and the for- Copies of this patent may be obtained for five cents each by addressing the ward wall of the ing semi-circular in form and provided with 1,

adjacent compartment bea slot at its inner face disposed transversely therethrough and in communication with the compartment, said slot being of an eX- tent in excess of the interior transverse diameter of the compartment, an elongated conduit operatively engaged with the inner end of the casting and in communication with the second named compartment, the inner end of the first named compartment being provided with a pocket, a fuel delivery pipe disposed through the conduit and operatively engaged with said pocket and in communication with the first named compartment, said first named compartment being of a depth materially less than the diameter of the bore of the delivery pipe, and means for admitting expansive fluid within the conduit, the discharge end of the first named compartment being in advance of the discharge end of the second compartment.

In testimonywhereof I hereunto aflix my signature in the presenceof two witnesses.
